GEORGE HEIDMAN, or omens-o, rumors;

BRAKE-GEAR moun'rmo.

Application filed November 15; 1926. Serial! No. 148,365.

My invention relates to mountings of the gear mechanism for operating the hand brakesof railway cars; that is to say theinvention relates more particularly to means for mounting the gear mechanism on the end sill of a railroad car underfraine.

The ob ects andadvantages of my invention will be readily apparent from the detailed description of the accompanyingdrawings wherein I Figure 1 1s a top planvrew OflllYll'lTPlOVQCi mounting secured to the underfra'nie end sillof which only a portion is shown.

Figure 2 illustrates the same in elevation. Figure 3' 1s a partlal' sectional view and side elevat1on, WlthttiPOTtlOn of end sill in section.

Figure 4; is a perspective view ofa support I ofatop:platesmelnben 11 having a flatupper surfacerat the inner end which is adapted to extend. flushwithxthe. bottom flange ofthe end sill memberlO and to terminate at the inner edge of thevlower flange ofthe end sill as shown in Figure 3.4

The. outer endlof the top plate may be slightly offsetas shown and is. provided with.

depending sides 12, 12.. The, upper surface of the top plate is provided. with a transversely dispnsed', flange or upstanding wall 13 reenforced by-webs or ribs l l; theflange 18 being adapted to extend flush with the outer face of the end sill and tobe riveted thereto. The top plate at theouter end is also suitably apertured to receive the brake st-alf, aportion whereof is shown at 15, and to provide suitable bearlngs for the drive element or gear 16 which also'has bearing" in aboss formation 17 on a, lower plate 18,

; see Figure 2.

Theouterend plate: 18 is provided with upstanding sides 19,19 preferably adapted to overlap the sides 12, 12. on the inner sides thereof and to: be riveted or otherwise secured thereto at 20; th e upstanding sides 19 being of a, height so that they may abut a ainst the bottom oftheztop plate and thus provide a suitable spaced relation hetween the plates to receive the drive element or gear 16. The botto plate 18 has an integrally disposed leg or portion 21 reenforced by means of lip22 the leg being preferably dis posed into a lower'horizontal plane to pro' vide sufhcient spacing for the driven element or gearQS and the, chain spool or druni24 while: the same time maintaining the driven gear in a proper plane relative'to the drive gear 16". The inner end ofthe legal isapert'ured to receive a pin 25 which ispreferably provided with a sleeveor spacing: nieinber 26' on which the driven elements, composed of drivengear and spoolv 24E, rotate; i

The upper end of the pin 25 is supported by means of, a bracket member or plate 27 which therefore also supports the driven ele; ments in place. The bracket member Q'Fis of an angular or stepped formation: more clearly shown in Figures 3 and 4 consisting of the lower horizon-tally disposed portion 28, apertu red at 29' to receive the upper end of the journal bolt or. pin 25, and the adjacent upwardly disposed portion 30, against which the inner end of'the top plate 11 abuts;

said portion also abutting against the inner edgeof the lower flange of the end sill 10. The upstanding vertically disposed portion 30 connects with the upper horizontally disposed portion 31 which is adapted to lap or' eXtendfflush with the top face of the lower flange of the end sill 10 and to berivet'ed thereto as'shown at 32. These rivets, if de sired, may alsoextend through the inner end of. the top plate 11'. The upperhorizontal surface 31 terminates in the upwardly disposed portion or wall 33 which is adapted'to extend flush with the inner side of,

the web of the end sill 10. The vertically disposed wall or portion 33 is preferably made to extend beyond the sides of the main portion of the bracket plate and these eX- tended ends, like the intermediate or main portion, are 'apertured at 34; to receiveythe rivets35 whereby the bracket is secured to the end sill ineniber 10. The rivets 35 are shown also einpleyed for riveting the up standing flange 13 of the top pl'atelto the end sill. The bracket plate 27 is shown provided with the side walls or flanges 36, 36 for reenforcing the plate.

, In order to perinitproper rotation of the driven elements 23, 24, washers 37, 37 may be employed It is apparent from the construction shown that the housing is securelyheld in place on the end sill and that the inward pulls or strains will be transmitted through the bracket plate 27 to the end sill; the stepped face of the bracket plate providing an abutting ledge for the top plate 11 of the housing.

It is apparent from the construction shown that removal of the drive and driven elements for repair or replacement may be readily accomplished without necessitating removal of the top and bottom plates of the housing or of the bracket plate 27, as the journal pin can be readily removed by unscrewing both nuts 25, therefrom (if a headed bolt is not used). The possibility of thus removing and renewing the gearing and chain spool or drum obviates the necessity of removing all rivets between housing members and the car end sill, with the result that a great saving in time, labor and expense is accomplished through the use of my structure: while at the same time a rigid thrust receiving bracket plate or member is provided adapted to withstand inward pulling strains.

In Figures 5 and 6 I illustrate a modified form of the invention wherein the top plate 38 is substantially similar to top plate 11 and provided with the upstanding flange 39 which is adapted to extend flush with the forward face of the end sill 10, with the inner end of the top plate 88 riveted at 40 to the lower inwardly disposed flange of the end sill and terminating with said flange. The mounting disclosed in Figure 5 also involves a bottom plate 18 which is identical with that shown in Figures 1 to 3; the top and bottom plates being provided with side walls at the outer ends which are riveted together as previously described; the two plates providing a suitable housing for the drive and driven elements which may be of any well known construction and actuated by means of a brake staff, a portion of which is shown at 15.

In this construction, the driven elements 23. 24 are journaled on the pin portion 41 of a bracket member 42: the pin portion 41, adjacent to the juncture between the vertically disposed lower end and the upper sloping end, being preferably provided with an integral shoulder 48, while the lower end is re duced and threaded at 44 to extend through a suitable opening in the bottom plate 18 and to receive a suitable nut as at 45. The upper sloping end of the pin, portion is shown formed integral with the laterally disposed plate portion 46 which is intended to lie flush with the web portion of the end sill 10 and to be riveted thereto as shown at 47 in Figure 5; these rivets preferably being the same rivets for securing the upstanding flange 39 to the opposite side of the end sill. The vertically disposed pin portion 41 is preferably the gear mechanism can be removed and replaced when found necessary by merely removing the rivets 47 without necessitating the removal of any other rivets; the ma or 7 portion of the housing or mounting therefore remainingintact.

The upper part of the pin portion of the bracket member 42 is shown circular in cross section above the shoulder 48, but it is evident that this portion may be of any cross sectional configuration as is also true in connection with the contour of the bracket member 27 shown in Figure 4; the constructions, however, being believed to be the simplest exemplifications of the invention which has been described in terms employed merely as terms of description and not as terms of limitation, as structural modifications are possible and may be made Without, however, departing from the spirit of my invention.

hat I claim is:

1. In a brake gear mounting, the combination of a top plate adapted to be secured to an end sill, a bottom plate secured to said top plate, drive and driven element-s mounted between the plates. with means for transmitting the pulling strains on the driven elements to the car end sill, said means involving a bracket portion adapted to be secured to the inner face of the end sill and depend across the inner end of the top plate and a journal portion for the driven elements removably secured to the bracket portion.

2. In a brake gear mounting, the combination of a top plate adapted to be secured to a car end sill, a bottom plate secured at one end to said top plate, drive and driven elements mounted between said plates, with means for rotatably supporting the driven elements in place and for transmit-ting pulling strains to the car end sill, said means involving an end sill engaging portion adapted to extend across the inner end of the top plate and a journal providing portion for the driven elements, said journal providing portion being adapted to receive the up-thrusts of the free inner end of the bottom plate.

3. A brake gear mounting comprising a top member, a bottom member, the two members being secured together in spaced relation, drive and driven elements rotatably mounted on the bottom member, means whereby the top member is secured to an end sill, and means for rotatably holding the driven elements in place, said means being formed to lap the inner end of the top member and to be secured to the inner face of the end sill. I

4. A brake gear mounting comprising a top member, a bottom member extending into a plane rearward of the top member, rotatable drive and driven elements mounted on the bottom member, and a bracket element arranged rearward of the inner end of the top member, with one end secured at the journal point of the driven elements While the other endis adapted to be secured to the car frame rearward of the point of connection between the top member and the car frame.

5. In a brake gearmounting, the combination of a top plate secured to a car end sill,

a bottom plate secured to the top plate, drive elements mounted between the forward ends of both plates, driven elements mounted on the rear inner end of the bottomplate, with means, independent of both plates, for trans niitting the pulling strains to the car end sill, said means depending below the inner end of the top plate and involving a journal portion for the driven elements, a bracket portion adapted to be secured to the inner side of the end sill to extend rearward of and depend beneath the plane of the top plate, and means for transmitting the Lip-thrust of the driven elements through the bracket portion to the car end sill.
